“Thomas Aquinas taught what was later called an ‘analogy of being,’ which grounds his account of how human language can be used in talking of God. Analogy is the alternative to ‘univocal’ and ‘equivocal’ language. A word is used ‘univocally’ when it means exactly the same thing in several different contexts, and ‘equivocally’ when it means different things in different contexts. ‘Leaf’ is used equivocally in the sentences ‘Put the leaf in the table’ and ‘Don’t pull that leaf off the tree,’ and ‘man’ is used univocally in the sentences ‘Socrates is a man’ and ‘Duns is a man.’ When applied to theological language, each of these alternatives is an unhappy one. If theological language is equivocal, then we cannot say anything true about God, but if it s univocal, God is reduced to the creaturely level.
Thomas believed that the solution to this was to say that theological language is ‘analogical.’ When we say ‘God is wise’ and ‘Socrates is wise,’ ‘wise’ is used analogically. We are not using ‘wise’ in exactly the same way, but we are not using ‘wise’ in completely different senses, either. There is an ‘analogy’ or ‘similarity’ between the two uses. Thomas applied this to all the attributes of God, including the fundamental attribute of ‘existence’ (Being). God’s existence is his essence, but this is not true of other beings. Thus, in the sentences ‘God exists’ and ‘My toenail exists,’ the word ‘exists’ is being used in an analogical way.
By contrast, John Duns Scotus (1266-1308) defended the ‘univocity of being.’ Though it pertains to theological language, the dispute has much larger implications. Scotus did not deny analogy per se. Terms are not predicated of God and creatures in exactly the same way, and Scotus believed that analogy is necessary because ‘creatures are only imperfect representations of the divine. Yet, he said that without some univocity within the analogy, there can be no analogy. In brief, ‘analogy presupposes univocity.’ More fully, ‘If of two things one is the measure of the other, then they must have something in common that permits the first to be measured of the second, and the second to be measured of the first. If of two things one excess the other by some quantity or degree, however great, then they must have something in common with respect of which the first exceeds the second….
Scotus argued that similar points must be true of our language about God and creation. God is more perfect than man, but that raises the question; a more perfect what? What is the common term? God is more perfect in ‘wisdom’ and ‘justice.’ But if this is to make any sense at all, then ‘wise’ and ‘just’ must be used univocally. Unless we are able to form a concept ‘wisdom’ that will encompass both God’s and man’s wisdom, the analogy is impossible….
In some respects, his (Scotus) arguments in favor of univocity seem correct, yet his treatement has radical implications for the relationship of theology and philosophy. Richard Cross points out that God’s ineffability, his transcendence of all our concepts of him, is weakened in Scotus’s account, so that ‘we can know quite a lot about God.’ That seems to put the case to mildly…. As a result God is paled on a continuum with his creation, and the Creator-creature distinction is blurred….
By distinguishing God and man as ‘two degrees’ (finite and infinite) of a single concept (‘being’), he flattens out the Creator-creature distinction….”

I bring this forward because I believe we are still stumbling over this issue today. Leithart lays out the contours of the issue but he doesn’t answer how to navigate through this epistemological problem.
It is interesting that Gordon Clark argues in a very similar way in one of his books that Leithart reveals Duns Scotus argued on the issue of univocal and analogical language.
As I’ve thought about the Van Til, and Clark blowout (which really remains with us today) I think the issue is captured by how Leithart lays out the issue. It seems to me that the issue is whether or not there really is such a thing as analogical language in a pure sense. In my reading it seems that Van Til used “analogy” in a way that fell off the equivocal side of analogical whereas Clark, when he used the word “analogy” fell off the univocal side of analogical.
If I am reading this correctly then the problem for Van Til and his disciples is that the Creator creature distinction becomes a barrier that no language can get through. On the other hand the problem for Clark and his disciples is, as Leithart notes concerning Scotus, the Creator – creature distinction is flattened out and the mind of man and the mind of God become one at every point of univocity in analogy.
Obviously a Creator-creature distinction that cannot be overcome by language and a Creator-creature distinction that really isn’t a distinction because it is conquered by the univocal in the analogical are both fraught with serious problems. The former is going to lean towards a unwholesome rationalistic theology while the latter is going to lean towards a unwholesome mysticism in theology.
Hey, I don’t have the answers (and apparently Leithart didn’t either) I’m just trying to lay out the ideological topographical map.
